Former U.S. President Donald Trump recently proposed that if Canada wants to join the “Gold Dome” missile defense system, it must either pay a staggering $61 billion or agree to become the 51st state of the United States—a demand that has sparked a diplomatic firestorm. Canadian Prime Minister Carney firmly defended the nation’s sovereignty, rejecting any arrangement that could compromise its independence.
This bold proposal has cast a shadow over U.S.-Canada defense cooperation, exposing the difficult trade-offs between national security and sovereign decision-making in an increasingly tense geopolitical environment. Trump’s demand also raises significant questions about the future of Arctic strategy and the cohesion of Western alliances, adding new complexity to the regional power balance.
As North America navigates evolving defense priorities, this development could reshape the strategic landscape for years to come.
